Abstract

Die vorliegende Erfindung betrifft eine Muffenverbindung zur Verbindung zweier Rohre, Rohrformstücke oder dgl., mit einem dem einen Rohr (14) zugeordneten Muffenende (16), in das ein Spitzende (60) des anderen eine Stützleiste (64) aufweisenden Rohrs (62) einführbar ist und das einen radial nach Innen ragenden Rand (20) mit zumindest einer ringsegmentförmigen Ausnehmung (26) aufweist, und mit einer Verriegelungsvorrichtung (40) zum Verriegeln des Spitzendes (60) in dem Muffenende (16), indem sich die Stützleiste (64) an der Verriegelungsvorrichtung (40) und diese an dem Rand (20) abstützt, wobei die Verriegelungsvorrichtung (40) zumindest zwei ringsegmentförmige Verriegelungselemente (42, 44) und ein Halteelement (46) umfaßt. Die Muffenverbindung zeichnet sich dadurch aus, daß die beiden Verriegelungselemente (42, 44) an jeweils einem Ende (49) ein in axialer Richtung sich erstreckendes Anschlagelement (50) mit einer in Umfangsrichtung sich erstreckenden Nase (56) umfassen, wobei die Anschlagelemente (50) in die Ausnehmung (26) des Randes (20) ragen und als Anschlag dienen, und das Halteelement (46) aus einem flexiblen Material unabhängig von den beiden Verriegelungselementen (42, 44) vorgesehen ist und als Abstandshalter für die beiden Verriegelungselemente (42, 44) dient.

Figure 00000001
The present invention relates to a socket connection for connecting two pipes, pipe fittings or the like. With a socket end (16) assigned to one pipe (14), into which a spigot end (60) of the other a pipe (62) having a support strip (64) can be inserted and which has a radially inwardly projecting edge (20) with at least one annular segment-shaped recess (26), and with a locking device (40) for locking the tip end (60) in the sleeve end (16) by the support strip (64) on the locking device (40) and supports it on the edge (20), the locking device (40) comprising at least two ring segment-shaped locking elements (42, 44) and a holding element (46). The sleeve connection is characterized in that the two locking elements (42, 44) each have at one end (49) an axially extending stop element (50) with a circumferentially extending nose (56), the stop elements (50 ) protrude into the recess (26) of the edge (20) and serve as a stop, and the holding element (46) made of a flexible material is provided independently of the two locking elements (42, 44) and as a spacer for the two locking elements (42, 44) serves.
